not notice, to add interest and increase knowledge by 
communicating their observations. There is scarcely a mi- 
croscopist possessing enthusiasm, or who works thought- 
fully, who has not found some little device of his own 
designing useful to him, or some process which has en- 
abled him to produce more satisfactory results than by 
stereotyped means. Readers of these notes would al- 
ways appreciate a short description of such methods, and 
by the communication of such ideas increased perfection 
would be attained. 
PRACTICAL.—If microscopists generally can but be in- 
duced to become practical workers, that is, to prepare 
and mount their own slides, an increased interest and 
wider knowledge would be the result, The difficulty in- 
varibly is that suitable material cannot be procured; as 
an instance of this, I may mention that in the April num- 
ber I offered to send a correspondent a small supply of 
Polcystina, and later mentioned that a supply was at the 
disposal of others. The applications that I received for 
samples indicated that there are numerous readers will- 
ing and anxious to mount their own specimens. Yetan- 
other instance; I have a letter from a correspondent, 
from which the following is an extract:— | 
“T hoped during the past summer to have been able to 
collect some specimens of Mycetozoa, but have not found 
one. What I want to suggest is that those collectors of 
such fungi who live in districts where they are found 
. abundantly, should distribute their findings to those who 
are not so fortunate, by way of exchange, or for my own 
part I would willingly reimburse any expense in sending, 
as I should much value even a small collection. There 
must be many who have neither time nor opportunity of 
collecting who would gladly avail themselves of such an 
arrangement.” —Knowledge.
